What Is Type 2 Diabetes?
Type 2 diabetes is a chronic condition where the body either does not produce enough insulin or cannot use it effectively, leading to elevated blood glucose levels. Unlike type 1 diabetes (an autoimmune condition), type 2 is largely preventable and reversible through lifestyle change, particularly in its early stages (prediabetes).
Key Risk Factors
The strongest modifiable risk factors for type 2 diabetes are: excess body weight (particularly abdominal fat), physical inactivity, poor diet (high in refined carbohydrates and ultra-processed foods), and high blood pressure. Non-modifiable factors include age, family history, and ethnicity (South Asian, Black African, and Black Caribbean people face higher risk at lower BMI thresholds).
Prevention Is Possible
The landmark Diabetes Prevention Program found that intensive lifestyle intervention (7% weight loss + 150 minutes of exercise per week) reduced the risk of progressing from prediabetes to type 2 diabetes by 58% — more effective than the drug metformin (31%). Even a 5% reduction in body weight produces meaningful improvements in insulin sensitivity.
Frequently Asked Questions
What blood sugar level indicates diabetes?
A fasting blood glucose of 7.0 mmol/L (126 mg/dL) or above on two separate tests indicates diabetes. Prediabetes is 5.6–6.9 mmol/L (100–125 mg/dL).
Can type 2 diabetes be reversed?
Yes — for many people, significant weight loss (10–15% of body weight) can result in type 2 diabetes remission, meaning blood glucose returns to the normal range without medication. This is most achievable in the first few years after diagnosis.
Should I test my blood sugar if I have risk factors?
If you have multiple risk factors, especially a family history, abdominal obesity, or are over 45, speak with your doctor about a fasting blood glucose or HbA1c test. Early detection makes management and prevention of complications far more effective.
